Joint hinge, particularly for glass swinging doors
A hinge strip for double-action glass doors, with a fixed hinge portion, a door hinge portion pivotable about the fixed hinge portion, a pivoting axis penetrating the fixed hinge portion and the door hinge portion, a cam with at least one depression disposed at the axis, and a force-loaded roller that cooperates with the cam. To achieve a precise adjustment of the zero position of the door, the roller is disposed to be adjustable orthogonally with regard to the longitudinal axis of the hinge strip.
1. A hinge strip, comprising:
a fixed hinge portion configured as a bearing block;
a door hinge portion pivotable about the fixed hinge portion;
a pivot axis passing through the fixed hinge portion and the door hinge portion;
a cam disposed at the pivot axis having at least one depression; and
a force-loaded roller rotatably supported in a roller piston and adjustably disposed orthogonally with respect to a longitudinal axis of the hinge strip that cooperates with the cam,
wherein the roller piston is arranged in an axially movable manner in an adjusting cylinder.
2. The hinge strip according to claim 1 , wherein a camshaft forms the pivoting axis, wherein the camshaft is supported in a torque-proof manner in the door hinge portion.
3. The hinge strip according to claim 2 , wherein the door hinge portion comprises:
a first clamping plate;
a second clamping plate configured to mate with the first clamping plate to retain a door element; and
one or more journals arranged in recesses of the first clamping plate configured to fix the cam shaft in a torque-proof manner.
4. The hinge strip according to claim 1 , wherein the roller piston rotatably supporting the force-loaded roller is arranged in the bearing block.
5. The hinge strip according to claim 1 , further comprising a spring configured to act on the roller piston.
6. The hinge strip according to claim 5 , wherein the roller piston is arranged in a bore of the bearing block with radial play.
7. The hinge strip according to claim 6 , further comprising at least one adjuster configured to orthogonally pivot the adjusting cylinder with respect to the longitudinal axis of the hinge strip.
8. The hinge strip according to claim 7 , wherein the pivoting of the adjusting cylinder within the bearing block comprises deviating between about 0° to ±15° from the longitudinal axis of the hinge strip.
9. The hinge strip according to claim 1 , wherein the hinge strip is configured for double-action glass doors.
10. The hinge strip according to claim 1 , wherein the door hinge portion comprises:
a first clamping plate;
a second clamping plate configured to mate with the first clamping plate to retain a door element; and
one or more journals arranged in recesses of the first clamping plate.
11. The hinge strip according to claim 7 , wherein the pivoting of the adjusting cylinder within the bearing block comprises deviating less than ±15° from the longitudinal axis of the hinge strip.
